To` ALL WHOM iT MAY coNennN; p

Be it known that I, SAMUEL I-l. CoWLEs, of-Oakville, in the county ofLiteheld,.and in the State of Conneeticut, have invented acertain newand useful Improvement in Car-Couplings; and I do hereby declare thatthefollowing is a full, clear, and exact description thereof, referencebeing had to' the accompanying drawings, i

and the letters of referen'oe'marlsed thereon. In the annexed'drawings,making apart of this specification- Figure represents a seetiouof'aear-coupling, showing the lconstruction and relative position of itsparts.

A represents the draw-head,l provided with a daring mouth and a chamber,which is pivoted the drawhook B, and is'fastened the slotted guideC.`The draw-head A may be constructed in any of the ordinary forms andmanner. B represents-a peculiar-shaped draw-hook, as seen in thedrawings,pivoted in the chamber of the draw-head A, and is provided witha steel or other spring,l z, inserted in its back or upper side in suchmanner as will hold, and for thepurpose of keeping the front end of saidhook B down close to the lower side of the mouth of. the draw-head A.Itis also provided with a vertical 'pin or rod, g, wh'iohpas'ses upthrough the top of thedraw-head, andV is designed as a convenient handlefor-the purpose of raisingup the front end of the hook B to uncoupleears, whenever it may be desired to do so. C Vrepresents a metallicguide, screwedor secured to the top of the chamber in the druwfhead A,and provided n'ith aslot, e, in whichiits 4and. works the hook B, and isdesigned to hold the same steady and brace it against lateral strains.-It is placed far enough l back from the'mouth of the draw-head'A, sothat its face or frontl side is behind and -nearly'parafllel with the:catch of the hook B, and of such length that the link 1D may passbeneath it when pushed to'o far into the chamberl of the drawhead A.'The outer or front end of the hook B is bevelled from its upper side, sothat when the link D strikes it, it is pressed up, and the said linkpasses under and is caught by .the said hook B.

' I am aware that various-shaped hooks have been used within thedraw-head before, -somo of which are constrncted Vsniilarto the oneherein described i' I What I claim, and desireto secure by LettersPatent, is-

The slotted metal guide C placed within the mouth of the draw-head A, asspecified, and used in combination with the pivoted hook B,- the frontQi?- vwhich is bevelled from top to bottom, all constructed andoperating as set forth;

In `testimony` that-I claim the foregoing, I havejherennto set my hand,this 17th day of December, v1867.
